Al-a-carte would be a logistical nightmare if we got to choose individual channels as cable companies would have to program each converter for the channels a customer wants. Not to mention the increased cost of labor for taking orders and provisioning accounts so a-la-carte would actually drive costs up.
Digital set top boxes don't care how channels are bundled. They are enabled and disabled individually.
If subscription and unsubscription is integrated into the set-top box firmware, there's need for CSRs except to handle problems.
A bonus would be an AJAX web interface that would allow you to click and unclick your subscriptions, and automatically update your monthly bill total (including all the taxes and franchise fees).
